Nonsense. So much faith, with so little evidence or figures. Read the
Whole House Book by The Centre of Alternative technology. Do you read
Andy?

I'm talking about houses of the construction that people typically
have, not experimental stuff,

No you don't read at all. Once again, so much faith, with so little
evidence or figures.

If you do the heat loss (or gain) calculations for a brick and block
property with tiled roof, having ridiculous amounts of space wasting
insulation in the roof space is making no more than a tiny difference
when set in the context of what is gained or lost through the walls
and windows.

Figures and evidence please. Not rambling thoughts.
